Semtech; West of England; On-site; GBP 70,000 - 105,000; Full time

Job summary

Semtech Stansted is seeking a Senior Validation Engineer to design high-speed validation PCBs and validate next‑generation devices at 25Gbit/s and beyond. You will guide stack-up, layout, bring‑up and measurement, and produce clear validation reports.

You’ll work with seasoned engineers and industry-leading test equipment, taking part in validation reviews and shaping how devices are tested, from schematic to board bring‑up.

Qualifications

• BSc/MSc in Electrical/Electronic Engineering or HNC/HND with equivalent practical experience.
• Strong Cadence Allegro experience, covering schematic and layout.
• Proven high-speed PCB design: stack-ups, materials, controlled impedance and signal integrity.
• Experience designing and debugging RF and data comms PCBs.
• Able to stay focused and positive under pressure in a fast-paced R&D environment.
• A natural team player with good communication skills.
• Self-motivated and comfortable learning new tools and techniques independently.
• Strong attention to detail and an analytical, creative approach to problem-solving.

Responsibilities

• Design validation PCBs for new product evaluation using Cadence Allegro, from schematic capture and stack-up definition through to layout and release.
• Apply high-speed and RF design practice, including material selection, controlled impedance and signal integrity, to boards operating at 25Gbit/s and above.
• Bring up, debug and characterise RF and data comms boards in the lab.
• Carry out benchtop characterisation of new silicon and write clear, accurate validation reports.
• Help identify and select the right lab equipment for validating new products.
• Build test automation software in Python (or similar) to make measurements faster and more repeatable.
• Work closely with designers, product, test and applications engineers, and take part in validation review meetings.
• Support new product design meetings and help shape how devices are tested.
